BROOM-MACHINE.

SPECIFICATION forming part of Letters Patent No. 291,735, dated January 8, 1884,

Application filed June 1, 1883. (No model.)

To all 1077,0171, it may concern Be it known that we, FRANK S. I-IOY'r and PETER L. SroRoi-I, both citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Broom- Machines, of which the following is a specification, to wit:

This invention relates to an improvement in machines for holding broom-sockets while being wound; and it consists in the peculiar construction of the same, substantially as will be hereinafter. described.

In order to enable others skilled in the art I 5 to which our invention appcrtains to make and use the same, we will now proceed to describe its construction and operation, referring to the accompanying drawings,in which Figure 1 is a side elevation, and Fig. 2 an end elevation, of our machine; Fig. 3, an end view, and Fig. 4 a longitudinal section of the mandrel.

A represents the main frame of our machine, in the upper part of which is journaled a mandrel or hollow tube, B, which is provided with belt-pulleys I) b, which are connected by belts Z1 with similar pulleys, a a, on a shaft, A, in the lower part of the frame. The pulleys a a are of different size, and are arranged loosely upon their shaft, and between them is a double clutch, a, sliding on said shaft and operated by a foot-lever, A to engage with either one ofthebelt-pulleys a a to impart motion to the mandrel B.

On the outer end of the shaft A is a driving-pulley, a', to which power maybe applied from any suitable motor. The forward end of the mandrel or hollow tube B is formed with four or more narrow slots or cuts, 0, extending horizontally, and the parts of the mandrel so formed are adapted to spring together, and thus make the circumference at this end smaller than at any other point. The inner side of the hollow mandrel is also formed conical, as seen in Fig. 3, at c, with the base or larger end of the cone toward the rear end of the shaft,for apurpose which will be presently understood. The forward end of the mandrel is also formed with a number of small 50 notches, c, in its edge, for the engagement of the broom-wire.

Vithin the hollow mandrel B is a follower formed with a conical head, 0, adapted to fit within the conical interior portion of the mandrel, and a shank, 0, extending back through the whole length of the mandrel and out through its rear end through an opening in a screw-plug, B, securedinthe rim. Upon this shank is arranged a spiral spring, 0 hearing at one end against the plug B and at the other against the collar 0 upon the shank, by the action of which the head of the follower is kept normally seated in the conical end of the mandrel. A collar, D, upon the mandrel is secured thereto by a pin, (1, passin g through the collar through small longitudinal slots d in the sides of the mandrel, and also through the shank of the follower, as clearly shown by Fig. 3. The periphery of the collar D is formed with a groove, d with which engages a forked elbow-lever, E, fulcrumed upon the main frame and connected by a short lever, E, with the vertical arm of an L-shaped foot-lever, E

This machine is especially intended for forming that class of brooms in which the head is secured upon a socket in which the handle is afterward secured.

In operation the workman,by pressing upon the foot-lever, operates the elbow-lever and collar D to draw back the follower, allowing the slotted end of the mandrel to spring together. The socket is then placed in position upon the forward end of the mandrel, and, the foot-lever being released, the spring C throws the follower forward, its conical head forcing apart the end of the mandrel, and causingit to tightly hold the socket. The broom-wire being now secured in one of the smallnotches in the end of the mandrel, the machine is started and the broom-head formed and wired upon the socket in the usual manner. hen fully formed, the foot-lever is again depressed, the follower drawn back, and the spring end of the mandrel comes together, releasing the socket, which is immediately replaced by another, and the operation is repeated.

The conical head of the follower may, if desired, be formed with ribs, and the mandrel with corresponding grooves which will insure their turning together without too much strain upon the pin (1.
